Company email (September 2017)
"No fining ingredients at all - the wines are vegan.

"Only two (La Zingara and The 12 Bar King) might have been [non-vegan], as we bought those in bulk rather than making them ourselves, and they are clearly called out on the menu as being conventionally produced."

[Note: formerly known as Vinavanti]

Note from Tracy (May 2014):
"I recently visited Vinavanti winery in San Diego. They are very small, but they are vegan! They don’t use anything to fine the wine!"
